In the old days film makers had to hand sculpt and paint every facial appliance, but with the latest 3D printing technology the team was able to produce approximately 40,000 different faces.

One type of heads in the film is called replacement animation, a technique that uses a series of different moulded faces for changing expression. These heads have faces held on with magnets so they can easily removed or replaced.

With the use of four 3D Systems' Z Printer 650 3D printers, the team was able to print the models in full color. Here are some very interesting numbers: the team used a total of 8000 lbs of printing powder, 77 gallons of superglue, 300 puppets, 40,000 faces, 50 stages, 5000 X-Acto blades, 66,400 rare Earth magents, 729 sheets of sandpaper, 2 gallons of white resin, 25,000 purple gloves and 1 massive warehouse! Wow!

New technology makes stop-motion filmmaking easier, and it also gives filmmaker a huge creative space. 3D printing technology pushes the film industry forward by changing the way how stop-motion animation is made. The characters have no longer limits in the range of emotions he could express, thanks to the latest 3D printing technology.
